What a disgusting and manipulative man BM is.
Totally USED his daughter in that situation - placed her between himself and Lauren, trashed Suzanne's family (who are also his daughter's family) in front of his daughter, scared and angered her and then blamed Lauren for it, and made his daughter HIS protector from the scrutiny and inquiries of the press. Says one thing to Lauren and leads his daughter to believe something totally different.
EVERYTHING Barry said was to pull his daughter closer as his protection and to alienate her from others.
I hope they gain enough distance and separation from him that they are finally able to consider and see how they have been used by someone from whom they deserved so much better. And that they then consider whether some of those from whom they have been alienated (like Suzanne's family) might have been treated just as despicably by their father, so they should engage on their own and form their own opinions.
If Barry and those who enable the worst in Barry are all you have, you need better.
ETA: P.S. When he convinced the eldest daughter she needed to sign that petition for guardianship, it was himself he was serving. And at both daughters' expense.
